Batch size: 13.3 ± 1.7 range: 1–48 (n = 52) Mean realised fecundity: 82.3 ± 9.0 Incubation time (days): 26–27 (on moistening) Batch configuration and attachment : Attached singly, short rows, groups, slightly shingled (Fig. 323). Colour: Pale bluish green, becoming darker and unmottled then transparent greyishbrown before eclosion (Fig. 323). Size (mm): (n=27) L=1.25 ± 0.07, W=0.90 ± 0.05, T=0.69 ± 0.06 Width/length: 0.72 No. of females: 3 Aeropylar opening size (m) (n=6): L=0.95 ± 0.00 Relative aeropylar opening size: 0.9 Micropyles : Indistinct (Figs 324 & 325) No. of openings: 6 No. of cells in rosette: 10 No. of rows of cells in micropylar area: 4 Shape: Narrow, elongated, bluntly ovoid, posterior pole sub­acute, wide (Figs 323, 326 & 327); polar profile circular (Fig. 324); wedge­shaped in profile; anterior pole truncated (Fig. 327), slightly angled to horizontal axis (Fig. 326). Characteristics : Egg marked on all surfaces by slightly convex hexagonal cells (Figs 326 & 327). Cell walls narrow, recessed (Fig. 328), except unelevated or recessed on lateral sides (Figs 329 & 330); micropylar cell walls narrow, slightly elevated; primary and secondary cell walls recessed (Fig. 325); cells in middle of top of egg slightly concave. Aeropyles irregularly shaped, unelevated, openings very small, inconspicuous (Figs 329 & 330), present on all surfaces apart from middle of top of cell. Micropyles slightly offcentred (Fig. 324). Anterior pole circumscribed with raised rim (Fig. 326). Chorion rough, pitted, wrinkled (Figs 328–330).
